Unwilling Sacrifice

You summon an invisible presence. This presence desires bloodshed. Choose any number of creatures within a 40-foot cube within range. Each creature inside the cube makes a Strength saving throw. On a success, nothing happens. On a failure, the creature becomes a sacrifice. Each sacrifice immediately begins to float 1 foot in the air, and takes 10d10 Necrotic damage as the blood in their body erupts from them like a fountain.

You may then choose a number of creatures equal to give a blessing equal to the number of sacrifices. These creatures are blessed with a shower of the sacrifices’ blood and gain a number of temporary hit points equal to half the damage a sacrifice took.
